GERGELY MRKUS, OF ELLWOOD CITY, PENNSYLANIA.

WRENCH.

To all whom tm/ay concern:

Be it known that I', Garantir MrlgUs, a subject of the King of Hungary, residing at Ellwood City, inthe county vof L'awrence and State of Pennsylvania, have invented certain new and useful Improvements 1n 'Wrenches of which the following is a specilication, reference being had therein to the accompanying drawing.

This'invention relates to wrenches, and my invention aims-to provide awrench with a revoluble head supporting adJu'stable jaws that can be easily and quickly placed in engagement with the(facets of a nut and then the head of the wrench revolved to turn a nut upon a bolt. f l The invention further aims to provide a wrench the 'jaws of which can be inserted inv an opening or socket containing a nut' or rotating the nut the Wrench-bung used! 1n places inaccessible to an ordinary wrench,`

' The invention still further aims to accomplish the above results by `a combination of mechanicall elements that will be hereinafter specifically described and then claimed.

Reference will now be had`to the drawing wherein Figure 1' is a vertical sectional view of thewrench, Fig. 2 is a horizontal sectional view of the same, and Fig. 3 is a front elevation of a portion of the handle of the wrench.

A wrench in accordance with thisinven` tion com rises la tubular handle 1 having the inner end thereof enlarged, as at'2 to provide a hand grip. The outer end of the handle 1 is -provided with a rectangular frame v3 and a bearing 4, saidbearing havingl an extension 5. The wall 6 of the frame ..3

as a socket 7 and extending into said socket is the outer end of a rotatable shaft 8 which is loosely lmounted in the tubular handle 1. The outer end of the shaft 8 has an annular groove 9 into which extends a screw 10, carried by the frame 3 to revent the shaft 8 from becoming accidenta ly displaced. The inner end of the shaft 8 has a crank 11 by said s aft can beV rotated within the tubular handle.

Slidabl mounted upon the shaft 8 and -rotated t ereby is a double beveled gear comprising beveled gear wheels'l and 14 which are arranged 1n spaced relation with other so as toprovide therebetween an annular groove 15. Extending Specification of Letters Patent.

Application yfiled March 14, 1912. Serial No. 683,785.

irovided with a handle 12, wherelatcnted Ang. 261, i912.

into the groove 15 are inwardly projecting and oppositely disposed pins 16 carried by a engage 1n notches 24 provided therefor in` the walls of the groove 20, adjacent to the ends thereof. The ins 23 are adapted to lock the double beve ed gear wheel either at the inner of the frame 3 or at the outer thereof,l said beveledgear wheel being shifted throu hthe medium of the yoke 17.

Journa ed in the bearing4 is the stub shaft 250i a rotatable head 26. The stub shaft 25 is provided with a beveled gear wheel 27 and this, beveled gear Wheel is adapted to mesh with the beveled gear 13, when the latter is at the outer position within the frame 3. The head 26 has a longitudinal groove '28 T -shaped incross section, and at one end of said head there is a xed arm 29 and at the opposite end a detachable arm 30, said detachable arm being held in engagement with the head by, a screw 31 or other fastening means. Rotatably mounted in the arms 29 and 30 is a right and left hand screw threaded rod or screw 32, the outer end of said screw having a head engaging the detachable arm 30 the inner end of said screw having a small beveled gear wheel 34. Slidabl mounted in the groove 28 of the head 2) are the tongues 35 of adjustable jaws 36 and 37, said jaws being moved to and from one another by rotating the screw- 32. The front side ofthe handle l is provided with aboss 38 and mounted in said boss is a pin 39. Rotatably mounted upon the pin 39 is the hub Ll0 of beveled gear wheels 4l and 42, the latter meshing with the beveled gear wheel '34. The beveled ear wheel 41 is adapted to mesh with the eveled gear' wheel 14, when the latter is at the inner end of the frame 3.

The front side of the extension 5 is provided with a socket 43, said extension having an opening 44' in communication with said socket, and the rear side of said extension has a notch lo adjacent to the opening-44. Arranged within the openincf 44 is a locking pin 46, said pin having the end Fig. 1 ofthe drawing, the handle l2Y can be 'wheels 41 and 42, the gear wheels 34 and `thereof provided with a head or knob 47,

Encircling the pin 46,.between` the socket member 49 andthe extension 5, Ais a coiled" spring 51. vThe end of the pin 46 is .adapted to engage in arecess 52 providedtherefor in the rearside of the,v head 26, 'said pin. locking the head26 whereby it cannot re-v volve. To release the head 26', it" is .only necessary to pull outward upon -thepin '46 andslightly rotate the same, whereby the lug will engagethe vrear side of the eX With the wrench in the position shown in rotated to impart a rotary movementjo the shaft 8, the double beveled gear, the gear the screw 32 to adjust the j aws `36'and 37. After the jaws have been moved into engagement with the facets of a nut, theA locking pin 46 is withdrawn from the recess 52 and then the double beveled gear is shifted to the outer end of the frame 3, whereby the beveled gear wheel 18-will mesh with the' beveled gear ,wheel 27, the beveled ear wheel 13 being: retained in the outer en of the frame 3 by the spring pressed pins 23 engaging in the outer notches 24. When the handle 12 is rotated and a rotary movement imparted to the shaft 8, the shaft 25 is r0- tated thereby rotating the head 26.v As the jaws 36 and 37 are carried by the head, the nut will be screwed or unscrewed upon the bolt. In orderthat the jaws 36 and 37 can be adjusted, it is necessary that the locking pin 46 holds the head 216 and that the beveled gear wheel 44 be in engagement or mesh with the beveled gear wheel 41.

It is thought that the operation and utility of the wrench will be apparent without further description, and while in the drawing there is illustrated a preferred embodiment of the invention, it is to be understood that the structural elements thereof are susceptible to such changes as fall within the scope of the appended claims.
